Answer:
Element Symbol Atomic Mass # of Atoms Mass Percent
Chlorine Cl 35.453 2 29.670%
Calcium Ca 40.078 1 16.770%
Oxygen O 15.9994 8 53.559%
Explanation:
color (intensive)
density (intensive)
volume (extensive)
mass (extensive)
boiling point (intensive): the temperature at which a substance boils.
melting point (intensive): the temperature at which a substance melts.
Answer:
8.68 L is the new volume
Explanation:
You use Boyle's law for this.
= first pressure
= second pressure
= first volume
= second volume
Convert pressure from atm to mmHg (use same units):
5.97 x 760 = 4537.2 -> 4.54 x 10³
...maintain 3 significant figures in calculation, and round as needed...
(4.54 x 10³ mmHg)(2.79 L) = (1460 mmHg)()
(4.54 x 10³ mmHg)(2.79 L) / (1460 mmHg) = = 8.68 L
Hope this helps :)

Answer:
.0556 L
Explanation:
First, convert the 1.35 M to 1.35 mol/L in order for the units to correctly cancel out.
Then, multiply (0.0725 moles Na2CO3/1) times (L/ 1.35 mol).
Finally, the answer will be .0556 L.
